## Magnetism and Matter NCERT Solutions

Q. Answer the following questions regarding earth’s magnetism:

a) A vector needs three quantities for its specification. Name the three independent quantities conventionally used to specify the earth’s magnetic field.

Sol. The three quantities are: horizontal component of earth’s magnetic field, magnetic declination and angle of dip.

b) The angle of dip at a location in southern India is about 18º. Would you expect a greater or smaller dip angle in Britain?

Sol. Great, because it increases from equator to poles.

c) If you made a map of magnetic field lines at Melbourne in Australia, would the lines seem to go into the ground or come out of the ground?

Sol. Coming out of the ground.

d) In which direction would a compass free to move in the vertical plane point to, if located right on the geomagnetic north or south pole?

Sol. Compass can point in any direction at poles.
